oh, just a wild guess since it was one of the first things that was focused on.
he didn't mention that she taught knitting classes, was a girl scout leader, a wonderful mother, and was also otherwise involved in various community activities. in the beginning, he never mentioned any of her wonderful qualities at all. in fact, all he talked about were what he viewed as her deficits and her "changing."
seems like he purposely left all the good out to me, yet the "anonymous friend" deemed it important to mention that she played online games and possibly formed an emotional attachment to someone. big whoop.
that planted the seed for many community members to believe that she just took off, when she was dead the entire time, IMO. and that planted seed had everything to do with her not being found for 84 days, in my opinion.
